I can get all of the parts off a truck 351W that is in the local yard if you need them.

I read a post on this site that 302 stuff was the same. I am not sure how that works since a 351W motor is taller and wider. My PS bracket on my 351W mounts to the water pump so if it was a 302 unit how could it bolt to the same point on the motor? I do not have mulitiple mounting points either on my brackets. My truck is an 89.

I had a friend that did a conversion on his old pickup...he went and got the main crank pulley from another somewhat similar vehicle that had the mulitple pulleys attached to it then measured fom the outside of that one to the outside of the others and just bought the belts he needed by the measurments. I have an 85 with the 302 multiple belts and the only oddball thing I see is that i think its the alternator pulley, is a dual pulley. One goes to the crank for turning and the other goes to the air pump to turn that. Otherwise, the crank pulley has only 3 pulleys, alternator, PS Pump and AC. (Or something like that). There should be replacement pulleys for the components so you can get em all running again on the individual belts instead of serpentine. When I get home i will post a pic of the belt configuration with and without A/C. (If I can figure it out). Then all you need to do is get the pulleys you need. Or replace the component if the pulley isnt removeable.
